[英]Toggle Off/On Google Fusion Layer (Google Javascript API v3)
我正在嘗試從Google地圖中的Google融合表中關閉/打開一個縣層（var縣），但是我一直在獲取要使用的代碼方面遇到困難。 我研究了一些有關如何執行此操作的示例，並在使用一個最新的代碼示例。 感謝您提供任何有關如何糾正此問題的幫助。 我附上我的完整代碼。 謝謝。

我的代碼出現了JavaScript錯誤： Uncaught TypeError: Cannot read property 'getMap' of null
要在HTML click事件監聽器中使用這些對象，它們必須位於全局范圍內（至少這是最簡單的，也可以使其與google.maps.event.addDomListener一起使用）。
您已經有這個：
var county=null;
var state=null;
您需要添加以下內容：
var map=null;
並從initialize函數內部的那些對象的定義的開頭刪除var關鍵字（這使新版本位於initialize函數的本地）。
